UFCThe Ultimate Fighting Championship (UFC) is a U.S.-based mixed martial arts organization, recognized as the largest MMA promotion in the world. The UFC is headquartered in Las Vegas, Nevada and is owned and operated by Zuffa, LLC. This promotion is responsible for solidifying the sport's postion in the history-books.
UFC is currently undergoing a remarkable surge in popularity, along with greater mainstream media coverage. UFC programming can now be seen on FOX, FX, and FUEL TV in the United States, as well as in 35 other countries worldwide.

The report comes from Yahoo! Sports' Steve Cofield, who stated Gonzaga has a staph infection. MMAjunkie.com (www.mmajunkie.com) could not immediately confirm the report.

The UFC hasn't officially announced the change to the bout, which was part of the event's Jan. 2 pay-per-view main card and set to take place at the MGM Grand Garden Arena in Las Vegas.

This the latest in a long string of injuries and illnesses that have plagued the UFC over the past few months. The Gonzaga vs. Dos Santos bout was a pivotal one for the UFC's heavyweight division, and the winner could have earned a title shot.

Gonzaga was returning to the cage for the first time since an August win over UFC newcomer Chris Tuchscherer. "Napao" cracked the UFC rookie with a low blow early in the fight, and Tuchscherer never full recovered. Regardless, Gonzaga had climbed back into title contention with a 3-1 record in his past four UFC contests and was looking for a win over one of the UFC's top prospects.

Dos Santos has quickly climbed up the ranks of the UFC's heavyweight division with three-straight stoppage wins in the organization. Just 25 years old, Dos Santos earned TKO wins over Fabricio Werdum and Stefan Struve before forcing Mirko "Cro Cop" Filipovic to verbally submit to strikes at a UFC 103 main-card contest in September.

UFC officials will likely keep Dos Santos on the card with a replacement fighter.
